Anthracyclines combined with cyclophosphamide or taxane-containing regimens may cause nail pigmentation which reduces quality of life in breast cancer patients. We conducted this study to investigate nail pigmentation and other skin changes associated with these drugs and aim to evaluate the effect of ice water immersion of hands on nail pigmentation. The first phase is an observational study. Breast cancer patients who received anthracyclines combined with cyclophosphamide or taxane-containing regimens for adjuvant/neoadjuvant chemotherapy are enrolled. The second phase is a prospective phase II study. Early breast cancer patients who plan to receive these drugs for adjuvant/neoadjuvant chemotherapy are treated with ice water immersion of the left hands while their right hands serve as control. The primary end point is the degree of nail pigmentation. The other end points are the incidence of nail pigmentation in both hands, the degree and the incidence of onycholysis, the time from the first chemotherapy to the occurrence of nail pigmentation/onycholysis, the recovery of nail pigmentation/onycholysis, and patient comfort.
The clinical study of modern therapies on flora changing in blood, oral cavity, urethra and intestinal tract of patients with malignant tumors. The study is observational. Patients are diagnosed cancer based on pathology or cell biology. The sample of flora will be obtained from their blood, oral cavity, urethra and intestinal tract, mainly to study what modern therapies lead to the influence of microecological environment including diversity and abundance of bacteria in patients who received malignant tumors. Immunological examination and Blood biochemistry evaluation include the number ratio, activity and function of immune cell, the immune cell marker(CD3, CD4, CD8, etc), C-reactive protein(CRP), tumor necrosis factor(TNF), Inflammatory stimulant factor(IL-2, IL-6, etc), tumor marker(CEA, AFP, etc),etc. Clinical evaluation includes image data(CT/MRI), quality of life(QOL), no disease progression survival, total survival, objective disease remission rate, etc.
This is a retrospective, multicenter, non-interventional study for the evaluation of real-world efficacy and safety of T-DM1 in metastatic/relapsed HER2-positive breast cancer as part of the establishment of hospital medical record collection system to evaluate drug effectiveness by Health Insurance Review & Assessment Service (HIRA). The medical records in approximately 1,000 patients of HER2-positive locally-advanced unresectable or metastatic breast cancer, who have received Kadcyla(Trastuzumab Emtansine, T-DM1) previously, will be collected.
This study is a single-arm, open, multi-center clinical study of nab-paclitaxel as the therapy ER+/HER2- recurrent metastatic breast cancer。
This research is being done because the investigators are looking for new and better ways to treat a type of breast cancer called triple negative breast cancer. This type of breast cancer can be more difficult to treat than other types of breast cancer as it does not respond to drugs such as hormonal therapies. One type of treatment that looks promising is immunotherapy using new drugs called immune checkpoint inhibitors. Immune checkpoints help to regulate the immune system and can stop the immune system from attacking cancer cells. Immune checkpoint inhibitors block this 'off-switch' and aim to help the immune system control the cancer. These drugs have been very effective in other cancers such as melanoma and are now being tested in breast cancer. In this study patients will receive an immune checkpoint inhibitor called avelumab. Half the patients on the study will also receive aspirin tablets for approximately 18 days as the investigators wish to compare the effects of avelumab alone versus in combination with aspirin. Patients will attend hospital approximately five times in order to complete all necessary study assessments. The first visit screens patients for suitability, after which a baseline visit will collect the first of two breast tissue biopsies. At the third visit a single dose of Avelumab will be given via an infusion (a drip in the forearm). Patients will then return approximately two weeks later for a second breast tissue biopsy before having a final follow up visit another two weeks later. Blood and urine samples will be taken at various visits throughout the study to help us learn more about the effects these treatments may have on the immune system and on breast cancer cells.
Geneswell BCT is a precise and qualitative in vitro diagnostic test. The expression of 9 genes was obtained from the formalin fixed paraffin embedded block (FFPE) of breast cancer tissue samples by RT-qPCR, and the patients were divided into high-risk group and low-risk group. This test provides prognostic information to assess the risk of recurrence. The BCT score calculated by geneswell BCT was associated with the risk of recurrence. The higher the BCT score, the more likely it is to relapse, and vice versa.
The purpose of this study is to evaluate the clinical efficacy of acupuncture on chronic upper limb lymphedema in patients with breast cancer surgery
With the development of neoadjuvant therapy for tumors, neoadjuvant chemotherapy (NAC) has become one of the most common and effective methods for preoperative systemic treatment of locally advanced breast cancer (LABC). Although epirubicin combined with cyclophosphamide and sequential docetaxel has been widely recognized as the first-line NAC for LABC, there are still some inoperable LABCs that are insensitive to chemotherapy and miss the opportunity of surgery, especially those with luminal A and low expression of Ki67. Therefore, neoadjuvant endocrine therapy has important clinical value for such patients. At present, the combination of aromatase inhibitor drugs and cyclin dependent kinase 4/6 can significantly improve the prognosis and survival of LABC compared with aromatase inhibitor monotherapy. However, whether inoperable LABC patients, especially those who are not susceptible to chemotherapy, can choose the combination of aromatase inhibitor drugs and cyclin dependent kinase 4/6 as neoadjuvant endocrine therapy to replace NAC remains unclear. Because the main principle of endocrine therapy is to induce tumor cell cycle arrest, leading to apoptosis of tumor cells, the effect is slower than that of chemotherapy. In addition, whether endocrine therapy can replace chemotherapy as a new adjuvant treatment for patients with inoperable LABC to improve the operability rate has not yet been fully evidenced. Therefore, this trial aims to conduct the prospective randomized controlled phase IV clinical trial of palbociclib combined with letrozole versus epirubicin combined with cyclophosphamide and sequential docetaxel as NAC to prove the efficacy of palbociclib combined with letrozole in postmenopausal estrogen receptor-positive LABC patients with low Ki67 expression.
This is a prospective, open-label , multicenter randomized controlled trial, with 248 cases in 50 centers planned for a period of 2 years. The aim of the study is to evaluate the safety and effectiveness of microparticles packaging chemotherapeutic drugs (MPCD) therapy on the treatment of malignant pleural effusion (MPE) in patients with advanced lung cancer or breast cancer.
